ROBAC SRM102 PM60 distributed by DKSH is an accelerator designed for polychloroprene rubber (CR). It is a safe alternative to ethylene thiourea (ETU). Vulcanizates cured with Robac SRM102 give properties comparable to those cured with ETU.

• It can cure CR through a wide range of temperature.
• It is a specially prepared blend of Robac SRM102 nominally 60%, in a polymeric binding system with very few, misshapes or fines.
• Additionally, it can be used to cure many other rubbers including ECO, EPDM, NR and CIIR.
• Using ROBAC SRM102 PM60 it is possible to reduce the zinc oxide levels in a CR cure system without affecting the physical or rheological properties of the final vulcanizate.
• It is available in Thailand and Vietnam.

BRUGGOLEN® C10 by Brüggemann is 17-19% sodium caprolactamate in caprolactam. Acts as a catalyst in the anionic polymerization of caprolactam. It is used along with an activator BRUGGOLEN® C20P (solid) or BRUGGOLEN® C235 (liquid). It enables the production of homogenous polyamide cast parts of a reproducible high quality with short production cycles (demolding after less than 10 minutes) and at low casting temperatures (melt: 110-140°C, mold: 130-170°C). It can be processed using cast film extrusion. The dosage level of BRUGGOLEN® C10 is 0.8 - 2.2 wt.%. The shelf life of the grade is at least 6 months.

• It is compatible with other additives like color masterbatches and UV-stabilizers.
• SILMASTAB AL2691 CAT is particularly suitable for insulation and sheathing for silane crosslinkable HFFR compounds.
• The recommended dosage level is 3-5% depending on the thickness of insulation & sheathing, and on the method to crosslinking (ambient or sauna).
• It does not contain any forbidden substance listed into the RoHS.
• It has a shelf life of 1 year.

Wacker® Catalyst N2 distributed by DKSH is a tertiary amine which has a strong influence on promoting the urethane (polyolisocyanate) reaction in a variety of flexible and rigid foam as well as CASE applications. It is used as a gelation catalyst.

• It effectively control the gelling reaction during foam formation.
• It imparts high level of activity and good physical properties with easy handling.
• Wacker® Catalyst N2 is used in a wide range of polyurethane foams, including flexible molded, semi-flexible, polyether slab stock and low-density spray foams.

Ken-React® KR® TTS supplied by FARRL is a titanate product based on titanium IV, class monoalkoxy, with isostearoyl functionality. It has low viscosity and solid content of min. 95%. It helps in adhesion promotion, coupling and dispersing of substrates (inorganics, organics, pigments, fibers, etc.), rheological adjustments of the base resin and filled systems, corrosion inhibition and improved acid resistance, improvement of flame retardants, metallocene-like catalysis and hydrophobizing of fillers and pigments in a wide range of applications. It is also available as dry-liquid powder under the name Ken-React® CAPOW® KR® TTS/H for powder-based productions and as pelletized masterbatch under the name Ken-React® CAPS® KR® TTS/L for productions based on pellets. Ken-React® KR® TTS is used in the processing of elastomeric, thermoset and thermoplastic polymers. The product has a shelf life of minimum 3 years after production. FARRL is the exclusive and authorized distribution and technical advisory service partner for Germany, Austria and all EU-CEE countries.

TYTAN™ AQ5000 by Borica is a proprietary titanium complex. Acts as an advanced polyesterification and transesterification catalyst based on the latest titanate technology.

• Offers reliable and high performance during the processing.
• It does not sacrifice on performance when water content is increased.
